Attached FBG Strain Sensor Based on Thermal Stress Mechanism
Based on a novel thermal stress mechanism, a attached FBG strain sensor with temperature-compensated function was designed and manufactured. This sensor cannot only compensate temperature drift but enhance stain sensitivity. The results are as follows: this package was shown to have a near 2.0 pm/°C shift and a high strain sensitivity of 1.9pm/με in this proposed self-compensated package.
